Conventions

SCATMECH assumes that harmonic fields have a implicit time dependence, exp(-it). Use of this convention [as opposed to that which assumes a exp(+ it)]. implies that the imaginary component of the index of refraction is positive. Multiplication of a field by i delays the phase by /2.

SCATMECH assumes that Jones vectors are represented using a specific right-handed basis set {x,y,k}, where k is the direction of propagation. For scattered light from surfaces, the right-handed basis set is {s,p,k} where s is perpendicular to the surface normal and the direction of propagation, and p is perpendicular to s and k.

Using these conventions, a Jones vector (1,i) represents a left-handed-circularly polarized wave.

Common Stokes vectors:

• (1,0,0,0) Unpolarized light
• (1,1,0,0) s-polarized light
• (1,-1,0,0) p-polarized light
• (1,0,0,1) left-circularly-polarized light

Jones vectors are normally operated upon from the left by Jones matrices.
